Chess on app

I play chess on app. I feel humiliated on loosing to app.

The following are the steps I follow

I open with queen pawn two steps.  Then knight and bishop move to enable early castling. 

Mid games are a series of feasible steps to mate the opposition king. Move this pawn so that this bishop has a path towards opposition king type of moves. Almost all my moves are developing focus on opposition king direction. 

At the right time I want to make a sacrifice and gain an advantage. 

I don't like end games.

I have a feel for who is better at an instant. 

Do you have better strategy? Are you guys liking the end games?
